The genus Willungia Powell, 1938 (Mollusca: Gastropoda: Cypraeoidea) and its assignment to the higher systematics

摘要

The validitiy and the assigment of the genus Willungia Powell, 1938, to the higher systematics is clarified. The genus is based on Willungia, tasmanica Powell, 1938, from the early Miocene of Tasmania. Cypraea ovulatella Tate, 1890, from the late Eoz?n of South Australia is also assigned to the genus. The assignment of Marginella fracta Tomlin, 1916, is doubtful because the species is based on a damaged and deformed holotype. Also the assignment of Willungia maoria Powell, 1938, from the Miocene of New Zealand cannot be confirmed because the shell morphology differs essentially from the type spezies.
